20120178402 | Optimized Limited Service Acquisition in a Multiple Subscription Device - Mobile devices, such as a dual standby global phone, can have multiple subscriptions to access different radio access technologies, such as Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) technologies. A selective scanning utility recognizes that emergency calls can be processed in any active subscription rather than being independently invoked to obtain a plurality of ways to make an emergency call. The utility limits service acquisition to just one of all active subscriptions in device, thereby achieving the objective of staying camped for limited service without needing to perform cell selection on emergency call origination on a secondary subscription at the cost of battery service. For single-radio devices, this solution also increases the availability of the first selected cell by avoiding the need to tune away for cell selection on the secondary subscription. | 07-12-2012 |
20120264425 | SELECTIVE BAND-SCANNING BY A MULTI-SIM USER EQUIPMENT (UE) IN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a wireless communications device (WCD) is provisioned with a plurality of subscriber identity modules (SIMs). The WCD determines a first set of bands (BAND | 10-18-2012 |
20130090137 | APPARATUS AND METHODS FOR REDUCING PAGE LOSS IN MULTIPLE SUBSCRIPTION, MULTIPLE RADIO ACCESS TECHNOLOGY DEVICES - Disclosed are methods and apparatus for reducing page loss in a multiple subscription, multiple radio access wireless device, such as a dual SIM wireless device. The disclosed methodology and apparatus determine whether a conflict will arise between paging channel information received from at least two or more subscriptions from two or more radio access networks using a single receiver in the wireless device. The reception for paging channel information via the wireless receiver is switched to receive the paging channel information from a neighboring cell for one of the two subscriptions when a conflict is determined. By switching reception of paging channel information to another neighboring cell, the likelihood of page collisions between two subscriptions is reduced. | 04-11-2013 |
20130176951 | RECEIVING CELL BROADCAST (CB) MESSAGES - A method for receiving cell broadcast messages is described. The method includes communicating with a first cell. The method also includes switching to communicating with a second cell. A cell broadcast channel is read after switching cells. The method further includes switching from a dedicated mode to a packet idle mode. The cell broadcast channel is reread once after switching from a dedicated mode to a packet idle mode. Other aspects, embodiments and features are also claimed and described. | 07-11-2013 |
20130208639 | APPARATUS AND METHOD FOR REDUCING POWER CONSUMPTION BY EARLY TERMINATION OF CELL BROADCAST DATA DECODING - The present disclosure presents example methods and apparatuses for conserving battery power in a mobile station. Some example methods may include receiving scheduling information from a network entity at the mobile station. In such examples, the scheduling information may include a scheduled final data frame. Furthermore, example methods may include receiving a final protocol data unit (PDU) of a service data unit (SDU) in an actual final data frame and comparing the scheduled final data frame to the actual final data frame. Moreover, in some examples, such methods may include initiating a sleep mode from the actual final data frame to the scheduled final data frame where the comparing indicates that the actual final data frame is earlier than the scheduled final data frame. As such, battery power at the mobile station may be conserved. | 08-15-2013 |
20140179255 | TECHNIQUES FOR POWER CONSERVATION IN EMERGENCY BROADCAST MESSAGE RECEPTION - Techniques are described for power conservation in emergency broadcast message reception in a wireless communications system. In accordance with a method for conserving power, one or more segments of an emergency broadcast message in an access stratum are received. The emergency broadcast message is identified as a duplicate emergency broadcast message based at least in part on one or more identifiers of the received one or more segments. The receipt of additional segments of the emergency broadcast message is terminated. | 06-26-2014 |

The method also includes switching to communicating with a second cell. A cell broadcast channel is read after switching cells. The method further includes switching from a dedicated mode to a packet idle mode. The cell broadcast channel is reread once after switching from a dedicated mode to a packet idle mode. Other aspects, embodiments and features are also claimed and described. | 10-16-2014 |
